通过C#发送截图

Question

我通过该代码捕获屏幕截图来保存。

Graphics Grf;
Bitmap Ekran = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height, PixelFormat.Format32bppPArgb);
Grf = Graphics.FromImage(Ekran);
Grf.CopyFromScreen(Screen.PrimaryScreen.Bounds.X, Screen.PrimaryScreen.Bounds.Y, 0, 0, Screen.PrimaryScreen.Bounds.Size, CopyPixelOperation.SourceCopy);
Ekran.Save("screen.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

然后将保存的屏幕截图作为电子邮件发送：

SmtpClient client = new SmtpClient();
MailMessage msg = new MailMessage();
msg.To.Add(kime);
if (dosya != null)
{
   Attachment eklenecekdosya = new Attachment(dosya);
   msg.Attachments.Add(eklenecekdosya);
}
msg.From = new MailAddress("[email protected]", "Konu");
msg.Subject = konu;
msg.IsBodyHtml = true;
msg.Body = mesaj;
msg.BodyEncoding = System.Text.Encoding.GetEncoding(1254);
NetworkCredential guvenlikKarti = new  NetworkCredential("[email protected]", "*****");
client.Credentials = guvenlikKarti;
client.Port = 587;
client.Host = "smtp.live.com";
client.EnableSsl = true;
client.Send(msg); 

我想这样做：如何通过 smtp 协议直接将屏幕截图作为电子邮件发送而不保存？

Answer 1

将位图保存到流中。然后将流附加到您的邮件消息中。例子：

System.IO.Stream stream = new System.IO.MemoryStream();
Ekran.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
stream.Position = 0;
// later:
Attachment attach = new Attachment(stream, "MyImage.jpg");

Answer 2

使用这个：

using (MemoryStream ms = new MemoryStream())
{
    Ekran.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
    using (Attachment att = new Attachment(ms, "attach_name"))
    {
        ....
        client.Send(msg);
    }
}
